Answer

Explanation:

Step1: Calculate total number of students

Total students = (7 + 12+11 + 18+3 + 19) [= 70]

Step2: Calculate number of students who got an A

Number of students with A = (7+18=25)

Step3: Calculate the probability

Probability (P=\frac{\text{Number of students with A}}{\text{Total number of students}}) [P=\frac{25}{70}\approx0.3571]

Answer:

(0.3571)
